AIR-PERMEABLE DOOR
To provide an air-permeable door capable of exhibiting high sound insulation performance with a simple internal structure.SOLUTION: An air-permeable door 10 is configured to be a ventilation structure in which both surface openings of a frame body 3 are closed by a first face plate 1 and a second face plate 2, and a first ventilation region 41 and a second ventilation region 42 are in fluid communication with each other via a door inner space 6. Vibrations of the first face plate 1 and the second face plate 2 are suppressed by first to third partitioning members 51 to 53 partitioning the door inner space 6, and a meandering flow path meandering up and down is formed between the first ventilation region 41 and the second ventilation region 42 to promote distance attenuation of propagation sound, thereby enhancing sound insulation performance.SELECTED DRAWING: Figure 1
【課題】簡易な内部構造で高い遮音性能を発揮できる通気性扉を提供する。【解決手段】通気性扉１０は、第１面板１と第２面板２で枠体３の両面開口を閉塞し、扉内空部６を介して第１通気領域４１と第２通気領域４２を連通させる通気構造とし、扉内空部６を仕切る第１〜第３仕切材５１〜５３によって第１面板１と第２面板２の振動を抑制すると共に、第１通気領域４１と第２通気領域４２との間に上下に蛇行する蛇行流路を形成して伝搬音の距離減衰を促し、遮音性能を高める。【選択図】図１
